The Relationship Between Forest Management And Stream Discharge In Mazumbai And Baga Ii Forest Reserves, Tanga Region, Tanzania, Shannon Duffy
The Relationship Between Forest Management And Stream Discharge In Mazumbai And Baga Ii Forest Reserves, Tanga Region, Tanzania, Shannon Duffy
Independent Study Project (ISP) Collection
Deforestation is known to alter hydrology by reducing interception, transpiration and infiltration capacity, and increasing runoff which all leads to higher stream discharge. For rural Tanzanian communities, surface water resources are crucial for meeting basic needs, so the integrity of headwater catchments need to be maintained to ensure their reliability. The objectives of this study were to a) map the streams in the two forests because none currently exist and b) determine the effect of deforestation on discharge variability. Over fifteen days of data collection, this study analyzed variability of discharge and the degree of correlation between discharge and rainfall …

Kleptoparasitism Of Shoebills Balaeniceps Rex By African Fish Eagles Haliaeetus Vocifer In Western Tanzania, Jasson John, Woo Lee
Tanzania Journal of Science
Kleptoparasitism is a specialised form of foraging interference occurring throughout the animal kingdom and especially is well documented among birds including African fish eagle Haliaeetus vocifer. However, only one record is reported between fish eagle and shoebill Balaeniceps rex despite their habitat overlap and it remains undescribed. This paper documents kleptoparasitism of shoebills by fish eagles in Malagarasi wetlands, western Tanzania. Kleptoparasitism was highly seasonal occurring in the dry season, especially at low floods. Both adults and non-adult eagles stole prey from shoebills, with non-adults initiating attacks at shorter distances than adults perhaps because of the lack of experience. The …

Profit Efficiency And Smallholder Sugarcane Out-Growers Under Contract Farming In Tanzania: Does Location Matter?, Thobias Nsindagi, Jennifer K. Sesabo
Journal of Humanities and Social Sciences
Tanzania is among countries that value the sugarcane sector as one of the potential crops for poverty alleviation. The sector provides direct employment to about 14,000 people, and it is an outlet for the produce of over 30,000 farming households (Nkonya & Barreiro Hurle, 2012). Likewise, it provides direct earnings and savings amounting to about US$28m annually (Sugar Board of Tanzania (SBT), 2007). However, sugarcane out-growers in Tanzania have been getting low prices relative to unit costs (Matango, 2006). This has generated substantial debate about the need and level of government support. Like other developing countries, contract farming (CF) has …

Breath Biomarkers And An Expanded Role For Isoprenoids In Plasmodium Falciparum, Chad Louis Schaber
Breath Biomarkers And An Expanded Role For Isoprenoids In Plasmodium Falciparum, Chad Louis Schaber
Arts & Sciences Graduate Student Theses and Dissertations
Malaria remains one of the deadliest infectious diseases worldwide, and efforts to combat it require novel insights into diagnostics, vector transmission, and drug inhibitor targets. Previous studies suggest that malaria infection causes hosts to preferentially attract the transmission vector, the Anopheles mosquito, but the mechanism and wider implication of these findings were not known. By analyzing the headspace above malaria parasite cultures, we identified several molecules that might engender mosquito attraction. We demonstrated that several of these molecules activate mosquito odorant receptors, including the known plant-emitted mosquito attractant _-pinene. During patient studies involving two independent pediatric clinical populations from Malawi, …

The Relationship Of Male And Female Pastoralist Income With Household Food Security And Nutrition Status In Tanzania: Maasai, Sukuma, And Barabaig Ethnic Groups, Henriette Gitungwa
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Although previous work provides a significant baseline for understanding the impact of gender on household decision making and resource (i.e. income and food) allocation, there are gaps in evidence for important groups, including East African pastoralists. Previous authors have noted that pastoralists’ gender roles and relations appear to be resistant to change, potentially impeding household development. This paper attempts to assess the relationship between male and female pastoralists’ income control and household food security and nutritional status in Tanzania. We use three surveys: a household-level livestock health and economics survey, a household food security survey, and an individual woman-level survey …

School of Biological Sciences: Dissertations, Theses, and Student Research
Abstract: Mucosal high-risk Human papillomavirus (HR-HPV) has been identified as the primary factor in causing cervical cancer, the most common cancer in women of low and middle-income countries (LMICs). Cervical cancer screening, incorporating the HPV test shown to be more advantageous than screening by visual inspection with acetic acid (VIA) alone. However, due to resources constrain these countries could not afford the available HPV tests. We, therefore, validated a cost-effective Multiplex PCR HPV (mPCR) assay, a recently developed assay for detecting sixteen genital HPV, fourteen HR-HPV and 2 low-risk genotypes. We postulate that this HPV multiplex assay will be at …
